Enhanced cell identification location determination

Abstract

Techniques for improving enhanced cell identification (E-CID) positioning are provided. An example of a method for determining a location of a mobile device according to the disclosure includes generating a plurality of receive beams with a mobile device, receiving, with one or more of the plurality of receive beams, a radio beam transmitted from a base station, such that the radio beam includes a beam identification value, and determining a measurement quantity for the radio beam for each of the one or more of the plurality of receive beams.

What is claimed is: 
     
       1. A method for determining a location of a mobile device, comprising:
 generating a plurality of receive beams with the mobile device; 
 receiving, with one or more of the plurality of receive beams, a radio beam transmitted from a base station, wherein the radio beam includes a beam identification value; 
 determining a measurement quantity for the radio beam for each of the one or more of the plurality of receive beams; and 
 determining a mean angle of at least one of the one or more of the plurality of receive beams relative to an orientation of the mobile device or relative to a coordinate system. 
 
     
     
       2. The method of  claim 1  further comprising:
 determining the location based at least in part on the beam identification value and the measurement quantity for the radio beam for each of the one or more of the plurality of receive beams. 
 
     
     
       3. The method of  claim 2  wherein determining the location includes providing the beam identification value and the measurement quantity for the radio beam for each of the one or more of the plurality of receive beams to a location server and receiving the location from the location server. 
     
     
       4. The method of  claim 2  further comprising:
 determining a beam width for at least one of the one or more of the plurality of receive beams; and 
 determining the location based at least in part on the beam width. 
 
     
     
       5. The method of  claim 4  further wherein determining the beam width includes determining a first measurement quantity for a first receive beam and a second measurement quantity for a second receive beam, wherein the second measurement quantity is 50% of the first measurement quantity and the beam width is equal to a width of the second receive beam. 
     
     
       6. The method of  claim 4  further wherein determining the beam width includes determining a first measurement quantity for a first receive beam and a second measurement quantity for a second receive beam, wherein the second measurement quantity is 50% of the first measurement quantity and the beam width is based on an angle between the first receive beam and the second receive beam. 
     
     
       7. The method of  claim 1  wherein the measurement quantity is a reference signal received power value or a reference signal received quality value. 
     
     
       8. A mobile device, comprising:
 one or more modems and antenna modules configured to:
 generate a plurality of receive beams with the mobile device; 
 receive, with one or more of the plurality of receive beams, a radio beam transmitted from a base station, wherein the radio beam includes a beam identification value; and 
 
 at least one processor configured to:
 determine a measurement quantity for the radio beam for each of the one or more of the plurality of receive beams; and 
 determine a mean angle of at least one of the one or more of the plurality of receive beam relative to an orientation of the mobile device or relative to a coordinate system. 
 
 
     
     
       9. The mobile device of  claim 8  wherein the at least one processor is further configured to determine a location based at least in part on the beam identification value and the measurement quantity for the radio beam for each of the one or more of the plurality of receive beams. 
     
     
       10. The mobile device of  claim 9  wherein the at least one processor is further configured to determine the location by providing the beam identification value and the measurement quantity for the radio beam for each of the one or more of the plurality of receive beams to a location server and to receive the location from the location server. 
     
     
       11. The mobile device of  claim 9  wherein the at least one processor is further configured to:
 determine a beam width of at least one of the one or more of the plurality of receive beams; and 
 determine the location based at least in part on the beam width. 
 
     
     
       12. The mobile device of  claim 11  wherein the at least one processor is further configured to determine the beam width by determining a first measurement quantity for a first receive beam and a second measurement quantity for a second receive beam, wherein the second measurement quantity is 50% of the first measurement quantity and the beam width is equal to a width of the second receive beam. 
     
     
       13. The mobile device of  claim 11  wherein the at least one processor is further configured to determine the beam width by determining a first measurement quantity for a first receive beam and a second measurement quantity for a second receive beam, wherein the second measurement quantity is 50% of the first measurement quantity and the beam width is based on an angle between the first receive beam and the second receive beam. 
     
     
       14. The mobile device of  claim 8  wherein the measurement quantity is a reference signal received power value or a reference signal received quality value.
